A hollow-fiber enzyme reactor, operating under isothermal and nonisothermal
conditions, was built employing a polypropylene hollow fiber onto which â-galactosidase
was immobilized. Hexamethylenediamine and glutaraldehyde were used as spacer
and coupling agent, respectively. Glucose production was… |

The dynamics of a quasi two-dimensional isotropic droplet in a cholesteric liquid crystal medium under symmetric shear flow is studied by lattice Boltzmann simulations. We consider a geometry in which the flow direction is along the axis of the cholesteric, as this setup exhibits a significant… |

The effect of a small gravitomagnetic monopole on (accelerated) circular orbits in the equatorial plane of the Taub-NUT spacetime is compared to the corresponding (accelerated) orbits pushed slightly off the equatorial plane in the absense of the monopole (Schwarzschild spacetime). |

We report recent results from a high-resolution numerical study of fluid particles transported by a fully developed turbulent flow. Single-particle trajectories were followed for a time range spanning more than three decades, from less than a tenth of the Kolmogorov timescale up to one large-eddy… |

The alpha-quartz polymorph of SiO2 forms the basis of mineral sands stable down to 100 km depths below the surface, making it of central geoscientific relevance. The characterization of the nanoscale properties of these materials is of importance, especially for elastic properties governing phonon… |

This work is concerned with the semiclassical approximation of the Schro¨dinger-Poisson equation modeling ballistic transport in a 1D periodic potential by means of WKB techniques. It is derived by considering the mean-field limit of a N-body quantum problem, then K-multivalued solutions are… |

We examine the constraints on the Yukawa regime from the nonminimally coupled curvature-matter gravity theory arising from deep underwater ocean experiments. We consider the geophysical experiment of Zumberge et al. [Phys. Rev. Lett. 67, 3051 (1991)] for searching deviations of Newton's inverse… |

In this paper we are concerned with the pointwise behaviour of functions in certain classes of weakly differentiable functions. We focus on first order Orlicz-Sobolev spaces and we establish optimal theorems of Rademacher type and of approximate differentiability type in this setting. |
